I was told that the voltage had to be higher than 6KV and those are only
400V. What is the Voltage that I can use and why?

Articles on capacitors for traps specify "transmitting"
type caps meaning high voltage ratings. I don't know
exactly the voltage rating required but it is in the
thousands of volts. That's why I used door-knob caps.

You can put capacitors in series to increase the
voltage rating but you also decrease the capacitance
and the voltages across each capacitor needs to be
equalized using resistors.
